Thanks for your mail. The scan files have been split out into a
separate package called dtv-scan-tables. Therefore I am reassigning it
to d-s-t. Oliver Schinagl (CC'd) is the upstream dtv-scan-tables
maintainer. I have reattached your cz-All-actual-2013 for his consideration.
Thanks,
Jon

Not 2/3. This I inappropriatelly got from the website. But it is
wrong. 3/4 is definitely correct. Change that so that we can actually
tune that multiplex.
The tuning parameters are different for multiplexes 3 and 4. And the
scan data are invalid for them. Further there are few more
transmitters built in here. Especially for mux 4. So it is added too.
